LEXVIS S. LEE, OF PHILADELPHIA, PENNSYLVANIA- l-iAlR-CLIPPlNG MACHINE.

QPECIEICATION forming part 01' Letters Patent No. 357,718, dated February 15, 1887.

Application filed June 19, 18F6. Serial No. 205,599. (No model.)

To all whom it may concern.-

Be it known that I, Lnwis S. LEE, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Hair-Clipping Machines, of which the following is a specification.

My invention has reference to hair-clipping machines; and it consists in certain improvements, all of which are fully set forth in the following specification and shown in the accompanying drawings,which form part thereof.

Hair-clipping machines have been made with a construction in which the cap was provided with an axle-pin for the operating-lever, but it was found in practice that this pin became worn,and necessarily caused a vibration to the cap, which caused the tension-nut to work loose, and thereby impaired the opera iveness of the clipper. It has also been proposed to place the pin upon the lower or stationary cutter-plate and secure it fast thereto and"journal the operating-lever thereon; but the movements of said lever caused the nut to work off and wear out the pin, and the fact that the pin was riveted to the lower or sta' tionary cutter-plate rendered it a difficult matter to resharpen the instrument. Aside from these constructions, it has been also proposed to center the lever upon a bushing depending from the cap and through which the tension-screw passes; but the objection to this construction is evident,in that the movements of the lever necessarily caused a vibration of the cap and its pin, causing the tension-nut to gradually become loose,as in the first instance.

My object is to overcome these difficulties, and thereby greatly improve the operativeness and lasting qualities of the instrument.

In the drawings, Figure 1 is a plan view of a hair-clipper embodying my improvements. Fig.2 is asectional elevation ofsame on line ma Fig. 3 is a sectional elevation of same on line 3 y, and Fig. 4 is a detailed plan View of the lever-axle with the nut removed to expose the method of preventing the washer from turning.

A is the lower or stationary cutter-plate. B is the upper or reciprocating cutter-plate. The stationary plate A is secured to flange D, terminating in a handle, 0, and is provided with a bushing, F, as a journal for the operating-handle E. The flange D is secured to the plate A by screws (Z, whereby the plate A may be removed, when desired, from the handle C for the purpose of being sharpened.

I is a removable bolt passed through the plate A and bushing F, and receives a nut, H, which retains the washer G down around the bushing and above the lever E. To prevent the washer turning, its holeis partly filled, as at g, which fits over a corresponding notch, f, on the bushing F. By this means the lever E works upon a fixed bushing irrespective of the means for securing it in place. The short arm 0 of the lever'E projects into a notch, Z), on the reciprocating cutter B, whereby it may bereciprocated by the operation of thelever E.

J is the cap, and is provided with the two pins M, which pass through slots N in the cutter B and enter holes on in the stationary cutter-plate A, the said pins acting as guides for the cutter B.

K is the tension-bolt, which passes through the hole in the plate A, slot k in the cutter B, and a hole in the cap J, and receives a tension-nut, L, above the cap,whereby the pressure between the cutters A and B may be adjusted. The cap J may rest upon the plate B, or,what is more desirable, it may have recesses P, which receive anti-friction rollers O, to re duce the friction between the cap J and the cutter B. The cap J is extended rearwardly, as at 9', forming a shield over the lever end 6, and is provided with a hole or notch, B, adapted to receive the not H, over or around which it fits, and thereby act as alocking device to prevent the said nut working loose. This construction also insures the cap against vibration, and thereby prevents any possibility of the tension-nut becoming loose, thus insuring the pressure between the plates remaining the same.

It is evident that after the cap has been removed in dismantling the instrument it may be used as a spanner or wrench with which to loosen the not H, and equally so it may be used to turn the nut in putting the parts together. The pins M project downward; hence in using the cap as a wrench it is necessary to turn it upside down, and if the hole It should be covered, as indicated in dotted lines, Fig. 2, it would be advisable to make a separate hole or socket, as indicated at R in dotted lines, Fig. 1, to be used as a wrench in unloosing or tightening the nut H. The extension j of the cap need not necessarily encircle the nut, as it may simply be notched to receive onehalf of the nut.

The feature of providing the cap with a spanner or wrench to suit the nuts on the machine is novel as far as I am aware and very important.

, cured to it, in combination with the recipro eating cutter, an operatinghandle journaled upon said bushing, a loosebolt passing through the lower stationary cutter-plate and bushing, anda removable nut upon its end above the operatinghandle, a cap above the cuttenplates, a clampingbolt to clamp the cap and cutters together, and anti-friction rollers between the cap and reciprocating cutter, substantially as and for the purpose specified.

2. In a hair-clippingmachine, the stationary cutter-plate provided with a bushing secured to it, in combination with the reciprocating cutter, an operating-handle journaled upon said bushing, abolt passing through the bushing, a nut upon its end above the operating-haudle, a cap having an extension forming a lock for said nut, and a tension-bolt for said cap and cutter-plates, substantially as and for the purpose specified.

3. In a hair-clipping machine, the stationary cutter-plate provided with a bushing secured to it, in combination with the reciprocating cutter, an operating-handle journaled upon said bushing, a bolt passing through the bushing, a removable retaining-washer surrounding the end of the bush above the handle, a nut upon its end above the washer to retain the operating-handle in position, a cap having an extension forming a lock for said nut, and a tension-bolt for said cap and cutterplate, substantially as and for the purpose specified.

4. In a hair-clipper, the combination of the stationary cutter-plate A, the handle 0, having plate D, and bushing F, secured to said cutter-plate, the handle E, to operate the movable cutter-plate journaled upon said bushing, a washer, G, surrounding the bushing above the handle E and stationary upon it, a loose bolt, I, passing through the stationary cutterplate and bushing, a washer, H, upon the upper end of said bolt above the washer, a reciprocating cutter-plate, B, cap J, a central tensionbolt, K, extending through both outt'er-plates and cap, tension nut L, and antifriction rollers 0, arranged at each end of the cap J, the whole being combined to form an operative machine.

5. In a hair-clipping machine, the combination of the stationary cutter having holes m, the reciprocating cutter having slots N N k, the cap J, having anti-friction-roller recesses P at its ends and pins M between the center and said rollers, and said pins passing through the slots N and entering the holes m, and being wholly protected from view and dirt, antifriction rollers O, and tension-screw K and its nut L, substantially as and for the purpose specified.

6. In ahair-clipping machine, the combination of the stationary cutter, bushing F, holes m, the reciprocating cutter having slots N N k, the operating-handle E, journaled on said bushing. a bolt, I, passing through said bushing, a nut, H, on said bolt above the operating -handle, the cap J, having a rear extension, j, having a hole, It, for said nutH,which it looks, and further provided with anti-friction-roller recesses P at its ends, and pins M between the center and said rollers, and said pins passing through the slots N and entering the holes m, and being wholly protected from view and dirt, anti-friction rollers O, and tension screw K and its nut L, substantially as and for the purpose specified.

7. The combination of the stationary cutterplate A, having holes at near its middle, the reciprocating cutter B, having the three slots N k N arranged in line and near the middle of the plate, the cap J, having guide-pins M M, which project through slots N N and fit into holes at m, and sockets P P near its ends and exterior to the pins, anti-friction rollers O 0, arranged within said sockets and pressing upon plate B, tension bolt K, extending through the plate A, slot 70, and cap J, and a tension-nut, L, whereby the rollerbearings shall press down upon the reciprocating plate near its lateral ends and outside of its guides, substantially as and for the purpose specified.

8. A hair-clipping machine provided with a cap having a portion thereof furnished with a spanner, wrench, or socket with which to loosen or tighten the nuts forming part of the clipper, whereby the clipper may be dismantled or put together without the necessity of providing other tools, substantially as and for the purpose specified.
